Earth core non-spring idling lever lock cylinder and locking technology thereof

Abstract

The invention discloses an earth core non-spring idling lever lock cylinder and a locking technology thereof. The lock cylinder structurally comprises a left lock body, a shaft lever rail, a lock cylinder protruding rail, an anti-explosion groove, a shaft lever channel, a dummy shaft lever channel, a right lock body, a lock body fixing rod groove, a lock body fixing rod, an outer lock cylinder lower assembly, an outer lock cylinder groove, an outer lock cylinder upper assembly, an outer lock cylinder fixing rod groove, an outer lock cylinder fixing rod, an outer lock cylinder shaft rod, an outer lock cylinder shaft rod groove, a shaft lever, an outer lock cylinder shaft rod rail, an inner lock cylinder front baffle, a key rail, an inner lock cylinder, an inner lock cylinder protrusion, a spring bolt thumbing piece, a recognizer, a key, key teeth and a recognizing hole. Compared with the prior art, the lock cylinder has the advantages that the lock cylinder can be suitable for safe boxes, safe cabinets, antitheft doors and other antitheft products, since the requirement for the manufacturing precision is slightly high, the lock cylinder is not suitable for frequently-used cabinet locks, box locks and the like without antitheft value and is extremely high in safety level.

Description

technical field [0001] The invention relates to the field of locks, in particular to an earth-centered springless idler lever lock cylinder and its locking technology. Background technique [0002] At present, the mechanical locks widely used in high-level anti-theft facilities (such as safes, safes, etc.) and with a high safety factor mainly include two categories: safe disc combination locks and switch gear blade locks. For a safe disc combination lock with 3 combination disks, the 3 combination disks are the active piece, the No. 1 passive piece, and the No. 2 passive piece from the inside to the outside, and each disk has a rectangular gap of the same size. It can make the lock bolt stopper fall into the gap under the condition of achieving password, so as to realize unlocking. But this code level is general, and the disc combination lock of 100 yards of 3 discs just reaches 1,000,000 kinds of code levels, but its shortcoming is relatively remarkable also. Taking a dis...

AI Technical Summary

Problems solved by technology

In addition, the displacement of the blades of the lock core of the two-speed switch itself is small, resulting in insufficient insertion and re-entry positions of the lock pin, so the lock pin should not be too long, which greatly increases the success rate of prying the door

For civil anti-theft facilities (such as anti-theft doors, etc.), the principle of mechanical locks such as pin locks and blade locks on it is relatively simple, and it is easy to unlock with technology. The password level is up to tens of millions under the same size lock cylinder. , are unable to achieve a high level of security protection
